Ab initio predictions for $^{12}\mathrm{C}$

Obtaining accurate predictions of nuclear structure starting from the interaction between constituent protons and neutrons is a complex, computationally demanding problem, particularly for resonances and continuum states. The \emph{ab initio} no-core shell model with continuum (NCSMC) explicitly builds in both short-range correlations as well as long-range clustering and collective dynamics necessary for accurately describing resonances and continuum states. We present predictions of, e.g., energies, phase shifts and capture cross sections, relevant for the $p+{^{11}\mathrm{B}}\rightarrow{^{12}\mathrm{C}}$ reaction obtained using the NCSMC with interactions from chiral effective field theory as the only input.
